For most of that historiography this was a historical moment characterized by the consolidation of peace and the strengthening of social contacts, economic and political partnership between the Mapuche people and border authorities, resulting in low war violence.

Yes it is...I'd say in Spanish "con la consecuente disminución de la violencia bélica" in this case the "reduction in conflict" sounds closer, however I would like to give a more specific concept with conflict. No people conflict or economic conflict, but war conflict...do you fallow me?
